This looks pretty awesome! It is also worth mentioning Django SQL Explorer (https://github.com/epantry/django-sql-explorer https://github.com/epantry/django-sql-explorer), which has all of the presented features, as well as handy schema definition by the side. It also allows for parameters in the queries, which is very useful (e.g. leaving the timeframe customisable before running a query). With Django 1.8 now being easier to install/deploy to wherever, this is a great plugin to allow more people data access!
